Replace segments
iterator replace( iterator from, iterator to, std::initializer_listinit);
This function replaces a range of segments with a list of segments in an initializer list. Reserved characters in the list are automatically escaped. Escapes in the list are preserved.
All iterators that are equal to `from` or come after are invalidated.
None of the character buffers referenced by the list may overlap the character buffer of the underlying url, or else the behavior is undefined.
Linear in `init.size() + this->url().encoded_resouce().size()`.
Strong guarantee. Calls to allocate may throw. Exceptions thrown on invalid input.
